Page 4: General Information
Scope of these instructions These instructions describe the installation, commissioning, function and the operation of the mixed HeatBloC MC42 / MC43 DN 40 and DN 50. For other components of the installation, such as the pump, the controller or the modular distribution manifold, please observe the instructions of the corresponding manufacturer. -
Page 5: Safety Instructions
2 Safety instructions 2 Safety instructions The installation and commissioning as well as the connection of electrical components require technical knowledge commensurate with a recognised vocational qualification as a fitter for plumbing, heating and air conditioning technology, or a profession requiring a comparable level of knowledge [specialist]. -
Page 6: Product Description
For the MC43, a nominal value for the flow temperature is set at the controller. The controller actuates the actuator on this basis. The PAW HeatBloC can be mounted on a PAW modular distribution manifold or on a PAW bracket. -
Page 7: Function
3 Product description Function MC42 / MC43 – HeatBloC with 3-way mixing valve The flow temperature of the heating circuit is controlled by the integrated mixing valve. Hot water from the boiler and cold return water are mixed to obtain the desired flow temperature of the heating circuit. -
